Q1. The coefficient of static friction between the coin and the disk is 0.50. Find out the linear speed of coin while it just begins to slip.
Q2. Two carts have a compressed spring between them and are initially at rest. One of the carts has total mass, including its contents, of 7.0 kg, and the other has total mass of 5.0 kg. If the 5.0 kg cart is moving at 3.0 m/s after the spring is allowed to push the carts apart, what is the velocity of 7.0 kg cart after free? The system is closed.
While a roofer is working on a roof that slants at 39.0 degrees above the horizontal, he accidentally nudges his 93.0 N toolbox, causing it to start sliding downward, starting from rest.
An underwater diver sees the sun 58{rm ^circ} above horizontal. How high is the sun above the horizon to a fisherman in the boat above the diver.
A kayaker needs to paddle north across an 85 m wide harbor. The tide is going out, creating a tidal current that flows to the east at 1.7 m/s. The kayaker can paddle with the speed of 3.0 m/s.
Find out the minimum horizontal velocity magnitude of the acceleration of the blocks
A 2.30-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 3.40sin (2pi*t), where F is in newtons and t is in seconds. The force constant of the spring is 35.0 N/m.
